Cov kawg khoom ntawm transcription yog RNAtranscript uas tuaj yeem tsim ib hom RNA hauv qab no: mRNA, tRNA, rRNA thiab tsis-coding RNA (xws li microRNA). Feem ntau inprokaryotes lub mRNA tsim yog polycistronic thiab hauv eukaryotes itis monocistronic.
Ntawm no, dab tsi yog qhov khoom kawg ntawm kev sau ntawv?
Dab tsi yog Qhov khoom kawg ntawm kev sau ntawv . Qhov kawg khoom ntawm transcription yog RNA, ib leeg-strandedmolecule ua los ntawm RNA nucleotides. Peb hom tseem ceeb ntawm RNAproduced nyob rau hauv lub kev sau ntawv yog mRNA, tRNA, andrRNA.
Ib yam li ntawd, qhov txiaj ntsig ntawm kev sau ntawv yog dab tsi? Cov ntaub ntawv noob caj noob ces ntws los ntawm DNA mus rau hauv cov protein, cov khoom uas muab lub cev rau nws daim ntawv. Qhov kev khiav ntawm cov ntaub ntawv no tshwm sim los ntawm cov txheej txheem sequential ntawm kev sau ntawv (DNA to RNA) thiab txhais lus (RNA rau protein). Thaum kev sau ntawv , tsuas yog ib txoj hlua DNA feem ntau yog theej.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog cov khoom ntawm transcription?
- Quora. Cov khoom ntawm transcription yog RNA. Qhov RNA tuaj yeem yog mRNA, tRNA, rRNA, lossis lwm yam RNA (xws li qhov uas ua rau miRNA, lncRNA, thiab lwm yam).
Dab tsi yog qhov khoom ntawm prokaryotic transcription?
Prokaryotic RNA Polymerase Plaub ntawm no subunits, denoted α, α, β, thiab β' muaj xws li cov polymerase core enzyme. Cov subunits sib sau ua ke txhua lub sijhawm muaj noob luam tawm , thiab lawv disassemble ib zaug kev sau ntawv tsis tiav.

Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov kev hloov pauv ntawm cov khoom uas txav ntawm qhov chaw mus rau qhov chaw ntawm - 12 m?
Kev piav qhia: Qhov kev txav ntawm ib qho khoom txav ntawm qhov chaw mus rau qhov chaw ntawm − 12 m yog 12 meters. Qhov kev ncua deb ntawm lub hauv paus chiv keeb mus rau qhov siab tshaj plaws txoj hauj lwm yog hu ua displacement ntawm ib yam khoom. Qhov siab tshaj plaws kev hloov pauv ntawm cov khoom nyob rau hauv ib nthwv dej yog hu ua crest thiab qhov tsawg kawg nkaus hloov pauv yog hu ua trough
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
